I believe you are talking about a common rail fuel system.It doesn`t send fuel to all injectors at once but the fuel pressure is 24,500 psi with a 26,500 relief valve for pressure spikes.If you are attempting to work on this engine yourself I would recommend taking it to a professional because of the safety risks when dealing w/pressures that high. The only diesel system that sends fuel at pressure to all injectors at once is a HEUI style injection system where high pressure oil and computer control deliver pressurized fuel into cylinder.Fuel pressure is max 80 PSI.Hope this info was helpfull.
What else can I help you with?
What are the constructional differences between an electronically controlled diesel system and a common rail diesel fuel system?
This question is kind of vague. Common rail diesel fuel systems are electronically controlled. A common rail fuel system has a high pressure pump that supplies the fuel at very high pressure to a single or common volume that all of the injectors are connected to. The injectors are then electronically signaled to operate, and draw their pressurized fuel from the common rail. The amount of fuel delivered is controlled by the injector. This system is somewhat similar to your port injection gasoline engine, but at much higher pressures. An electronically controled diesel that isn't common rail will have an injection pump that supplies high pressure fuel to each injector individually. The amount of fuel delivered is controlled electronically by the high pressure injector pump.
How is maintenance different for a gasoline and diesel cars?
The main reason is that the way Diesel and Gasoline engines works is complete different, the gasoline needs a spark to explode and generate movement. The diesel explodes with pressure, the pressure of the fuel on the cylinder is what makes the explosion, so in a diesel engine you don't need an electric system to generate a spark. The compression in a diesel engine is a lot higher that a gasoline engine. All diesel engines have diesel injectors, gasoline engine works with injectors and carburators. Because of all this differences and more the maintanence is different, oil change periods, air filters, fuel system, electric system, belts, valves.........
Would a faulty injector stop a BMW 3 series diesel from starting can it start on 3 injectors?
The 3 series BMW uses a common rail diesel injection system. This means a high pressure pump provides diesel to a common rail feeding all 4 injectors. If one injector goes down there can be insufficient pressure to start the car. The 3 series BMW uses a common rail diesel injection system.

What is the diesel fuel system in car?
The diesel fuel system in a vehicle is similar to the fuel system in a fuel injected gasoline driven car. There is a tank to hold the fuel, fuel lines to deliver it to the fuel pump, and fuel lines from there to the injectors that deliver the fuel into the cylinders at the correct time.
How can diesel get in the oil on a Cummins engine?
Usually bad injector cups. Leaking fuel seals, fuel system restriction, and bad injectors are other possibilities.
How can lack of oil pressure prevent my 7.3 diesel from starting?
Simply put these engines use an injection system called HEUI or Hydraulically-actuated, Electronically-controlled Unit Injectors. These injectors require a high pressure oil pump to supply the injectors oil pressure to actuate the internal injector piston to push fuel into the system. No oil pressure, no fuel.
How do you know which diesel fuel injectors are bad?
By doing a pressure and spray pattern check, this can either be costly or messy, depending on if you do it yourself or have them tested at a shop. Most times it is just a safe bet to replace all of the injectors on diesels, but I have to warn you if the diesel you are speaking of has mechanical injectors (no wires running to each injector) you may have a problem with the injection pump($$$$$), most common problems are the pump is out of time, or somewhere a seal is failing or has failed, or it needs a fuel delivery system cleaning and filter replacement. I have never actually heard of mechanical diesel injectors being replaced due to wear, although I am sure that has happened once or twice before.
Does the 1983 Chevy silverado Crew Cab 6.2 Diesel use a mechanical fuel injection?
Yes, It is a mechanical fuel injection system with an injector pump to pump fuel to the injectors.
How can remove the air in diesel engine fuel system?
you need to crack loose the injectors and let the fuel pump push some fuel (and air) out around them then tighten them back up.
Is bio fuel OK for Renault Kerax 420 dci common rail diesel engine?
i wouldnt go near a high pressure fuel system with bio you will damage the pump and injectors
What is the diesel leak off for on an injector?
The diesel leak off is for getting air out of the system should you run out of fuel. It is very difficult to get the diesel engine restarted after running out of fuel as compared to a gasoline engine which is relatively easy. Once you have run your diesel out of fuel, the injectors must be primed for you to have even a chance of getting restarted. So, VW/ Mercedes owners, keep that tank about a quarter.
What different of perform diesel engine tune up and gas tune up?
Diesel and gas engine tune-ups are quite different. For diesel engines, it’s all about the fuel injectors, glow plugs, and making sure compression is good. Gas engines focus more on spark plugs, the ignition system, and cleaning things like the throttle body. Diesel tune-ups are more about the fuel system, while gas ones are more ignition-focused.
